Why am I being denied a bank account in Thailand despite having a valid visa?

Denied bank accounts in Thailand, what's going on?

Interesting development on Friday. Went to Kalasin Immigration for paperwork for drivers license. It came up in conversation that I had been denied at several banks to open a bank account. Head of Immigration had another look at my 5yr DTV and got quiet angry. He said no, this is a good visa. He got a pen and circled the 5 year part of the visa, wrote his phone number and name on the bottom and said, if the bank refuses tell them to call me 😃. Looking forward to going to a bank tomorrow and see how it all plays out. Should be good for a laugh.
